How to Choose the Best Bug Detector 

Battery Life

The battery life of the RF bug detector is significant. Because nobody wants a device that will stop working within a few hours, check the battery life, and if you find detectors that can work for over 12 hours with a single charge, then go for it. (1)

Frequency Range

I think it is better to choose a bug detector covering broad frequency range spectrums. Some of the detectors on our list can cover from 1 MHz to 6.5 GHz. But few others can cover up to 8 GHz and 10 GHz. Pick the sensor that covers the spectrum of the devices you want to find. For example, GPS trackers operate between 824 to 846 MHz or 880 to 920 MHz. Bluetooth bugging gadgets operate between 2.4 GHz to 2.48 GHz. The Wifi communications utilize 2.4 GHz to 2.48 GHz. (2, 3)


The bug-detecting device has a modest interface and a few essential functionalities. For example, when the detecting device finds any surveillance appliance, it sends light alerts. Some advanced editions even come with colored strength meters to display and distinguish signal strength. 


One most underrated factors are the durability of the device. Most people will likely carry the device in their backpacks, purses, or pockets. Make sure that you buy a device that comes with a durable and sturdy construction so that it won’t break into pieces when you store or carry it. 


You can find RF bug detectors at a lower price, but some are too high. On average, most of them are between $50 and $500. So, before purchasing the device, look at the functions, accuracy, and other features to know whether it is worth spending some money on. 

Final Thoughts

Our practical list of RF detectors is best-rated and top-notch. They can easily detect the radio frequency emitted by hidden cameras, video, data, or tracking electronic devices. Also, the bug detectors are very sensitive to certain frequencies, which most spy cams and hidden recorders radiate. Some RF detectors on our list use some meters, while others use an attenuation circuit to detect the bug’s location. Still, we stick to Kunkin kk1 Anti Spy Detector because it ticks all the categories to be the best bug detector.
